VETERINARY SURGICAL INSTRUMENT.

Specification of Letters Patent.

Patented Aug. 24, 1915.

Application filed September 28, 1914. Serial No. 863,873.

To all whom it may concern Be it known that I, FRANK G. LANG, a citizenof the United States of America, residing at Bay City, in the county ofBay and State of Michigan, have invented certain new and usefulImprovements in Veterinary Surgical Instruments; and I do hereby declarethe following to be a" full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to a veterinary surgical instrument.

The device embodying the present invention is a file for use in filingthe teeth of animals. And it is the object and purpose of this inventionto construct a file of this character including many new and usefulfeatures which will be apparent as understanding is had of theconstruction as disclosed in the accompanying drawings, in which;

Figure 1 is a plan view of the instrument. Fig. 2 is a side viewthereof; and Fig. 3 IS a view from the opposite side of the instrumentas shown in Fig. 1.

Like reference characters refer to like parts throughout the severalviews of the drawing.

In the construction of the veterinary surgical instrument, there isprovided a handle formed of sections 1 and 2 which. are adapt ed to bedetachably connected together as indicated in the dotted lines wherebythe handle may be separated at will when not in use so as to occupysmall space. The section 2- has a tapered end 3 which passes between theears 4i and 5 formed integral with the retaining member 6. Thisretaining member is comprised of a base slotted from the end at whichthe cars 4 and 5 are formed to adjacent the opposite end as indicated at7, and said base has formed thereon at the sides, gripping members 7 and7* adapted to receive therebetween the file 9 as best shown in Fig. 3 ofthe drawings. The ear 4 and the end 3 of the handle are pierced toreceive a binding screw 8 threaded at its end and received in a threadedopening in the ear 5 of the retaining member. With this construction itis obvious that by operating the binding screw 8 the retaining membermay be located at a variety of positions with respect to the handle andheld in any of such positions by merely tightening the binding screw. Atthe same time, as the ears 4 and 5 are placed one at either side of theslot 7 the tightening of said binding sore-w will draw the opposed sidesof the retaining member toward each other and the file 9 held betweensaid sides will be firmly gripped thereby and retained in position. Thebinding screw 8 therefore accomplishes the dual function of securing thefile in the retaining member 6 and of holding the retaining member atany desired position with respect to the handle. If at any time theangular relation of the retaining member and the file held therein, withrespect to the handle, is to be changed, it may be accomplished bymerely loosening the screw 8 slightly, thereby permitting the pivotalmovement of the retaining member to the desired position after which thescrew may be again tightened to hold it in such position. Furthermore,if at any time it is desired to substitute a new file when the one inuse has become worn or is otherwise useless, this may be accomplished byloosening the binding screw to a greater degree whereby the slot 7 maybe widened and the sides of the retaining member spread apart freeingthe file, when it may be detached from the retaining member and a newone placed therein.

From the foregoing it is apparent that I have provided a veterinarysurgical instrument of this type which comprises but few parts and whichis very simple in construction and one in which the operation of asingle means secures the file at various an gu lar positions withrespect to the handle and also secures the file firmly in place in theinstrument. Modifications in detail may be resorted to Without departingfrom my invention which is defined in the appended claims.

I claim 1. In a device of the character described, a retaining membercomprising a slotted base and side members extending at right anglesfrom the base, the slot in said base extending from one end to adjacentthe other end thereof, a file in said retaining member between the sidemembers thereof, ears formed on the retaining member at either side ofthe slot, a handle having its end located between said ears, and meansconnecting said ears and handle, substantially as described.

2. In a device of the character described,

a retaining member comprising a slotted base and side members extendingatright angles from the base, the slot in said base extending from oneend to adjacent the other end thereof, a file in said retaining memberbetween the side members thereof, ears formed on the retaining member ateither side of the slot, a handle having its end located between saidears, and a clamping screw inserted through one ear and thehandle, andthreaded into the other ear, substantially as described.

3. In a device of the character described, a handle, a retaining membercomprised of a base and spaced apart gripping members projecting fromthe base at each side, a file detaohably held between the grippingmembers and a single means pivotally connecting the retaining member tothe handle and drawing the gripping members against the side edges ofthe file, substantially as described.

In testimony whereof I aflix my signa ture in presence of two witnesses.
